VEHICLE-TIRE.

To all whom 'it 'may concern:

Be it known that I, FRANCIS H.- HoL'roN, citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Vehicle-Tires, of which the following is a specification.k

My invention has reference to an improvement in vehicle tires adapted to take -the place of the pneumatic tire now in common use.

Tofthis end the invention consists in a tire which is provided with a specially constructed yielding member or part of a more or less cellular or equivalentformation and adapted to provide substantially the same kind and measure of resiliency that is obtained by the pneumatic tube and yet is proof against injury by puncture and very much more durable in service as well as being considerably less expensive in original cost, as will hereinafter fully appear.

In thepaccom-panying drawings, Figure 1 is a cross section of my new and improved tire, and Fig. 2 is a plan view of a portion A thereof partially sectioned olf at its periphery to disclose the internal construction. Fig. 3 is a perspective view of a segmental piece of the distinctively cushioning or yielding portion or part of the tire.

As thus shown the tire comprises four parts or portions consisting of the so-called clencher rim A, the outer tread tube or case B, the wooden or equivalent ring C and the resilient or cushioning member or portion D.

The rim A may be of any approved pattern or style but preferably is of a kind using a removable side portion or flange so as to facilitate the placing and removal of ring C, particularly when said ring is made of wood or like inelastic or inflexible material. If` however, said ring were constituted with more or less elasticity, say of'a low grade of rubber or the like or were tleX- ible so as to possibly be rolled over the last portion' of the rim engaged thereby, a clencher rim having fixed side flanges might be used. Otherwise a removable side flange for said rim is deemed the better construction for a wooden or like ring. Structur ally the said ring is approximately half round in cross section, conforming to its seat within the sides of rubber case B and,

to be exact, assuming a more or less V shape in this instance. The said outer side of said Specication of Letters Patent.

of which it is constituted, so as to secure,

the yielding,'spring or resilient member D thereon. This member in any event is con-v structed to fill out the other or outer half round space in cross section within case or or like material in one or more layers to which said strips are cemented and which in turn is adhered or cemented yupon the flat outer surface 4c of said ring. tical effect constitutes the parts C and D into a single. or unitary member of substantially cylindricalshape in cross section and lling out the space within case or tube B and sustaining the same relatively as seen in Fig., 1. The said rubber or equivalent strips or portions of member D are shown in this instance as of V shape in plan and projecting one within the other around the wheel in such relation that they have a certain space at all points between them even when compressed by a load, and that three or more of said strips will be involved in the tread when the load is upon them. .The half round shape of the said pieces in face elevation of course brings their points 5 to the central position of greatest depth radially and where the weight will be heaviest, and said points might be strengthened if found necessary by incorporating more stock therewith, but I have found that this is not required since said points lie in respect to each other as they do and ofucourse are made of a grade of rubber which, while it springs and is resilient in action. has body enough to stand up and carry the load without breaking down.

Of course the present construction is not to be regarded as the only one within my in- This in prac vention, for in fact it is but one form of I have referred to the? ring C as beingva substantially solid portion, say of Wood. or

i the like, but byths' I do'not mean that it may not be made out .of some other material or-materials or vof acomposition which will probably mclude more or less yielding material like allow grade of rubber incorporated v with more or less liber, the-object being to get lacheap and feirly firm base for the portion D.

By .vehicleV I mean to include bicycles, motor cycles and the like.

' Ring C isV not necessarily endless as it may be made'- in segments of a circle; and in.-y

deed if it be made of flexible material' adapt- Vcd to be bent circular-it may even be made in one straight connected pieces.
